RESUMEN
PURPOSE OF REVIEW: Adrenocortical carcinoma (ACC) is a rare, aggressive disease with a paucity of data and great variability between published studies regarding its treatment. This review provides information on current clinical management and oncological and endocrine outcomes. RECENT FINDINGS: Complete surgical resection is the only potentially curative treatment for adrenocortical carcinoma (ACC). Adjuvant mitotane treatment is recommended in patients with favourable/intermediate prognosis. As part of the endocrine follow-up, steroid hormones and thyroid hormones may be decreased or increased and may need to be substituted or suppressed. Recurrences are common. If the disease-free interval is more than 12âmonths, surgery is a treatment if complete resection is feasible. In advanced/metastatic ACC patients, the prognosis is poor. Mitotane monotherapy is only appropriate for patients with low tumour burden and indolent disease. Patients with unfavourable prognosis should be treated with aggressive cytotoxic therapy. Patients requiring third-line treatment should be considered for clinical trials. Immunotherapy and targeted therapy are currently being investigated, but have so far yielded only unsatisfactory results. SUMMARY: There is scarce evidence for the treatment of ACC, which often complicates clinical decision-making. Patients who progress on EDP-M should be treated in clinical trials.

PURPOSE OF REVIEW: Adrenal lesions are commonly discovered on abdominal imaging studies, whereas some patients with adrenal tumors present with symptoms of homonal excess. They are categorized as either hormone active or inactive and either as benign or malignant. This review is focused on the endocrine work up in patients with adrenal tumors. Knowledge of the use and limitations of hormonal assessment is essential for propper interpretation of the obtained test results. This article reviews which diagnostics are necessary to identify adrenal masses requiring treatment. RECENT FINDINGS: Delayed hormonal assessment is not uncommon and associated with delayed treatment. The endocrine work up is guided by data from prospective and retrospective observational studies. Adrenal tumors include a wide spectrum of diseases and as a principle, most patients require biochemical testing to select the appropriate treatment. SUMMARY: The most important factor for the outcome in the management of adrenal masses is, beside the exclusion of malignancy, a structured evaluation of the patients endocrine status.

BACKGROUND: Robot-assisted partial nephrectomy (RAPN) is used more and more in present days as a therapy option for surgical treatment of cT1 renal masses. Current guidelines equally recommend open (OPN), laparoscopic (LPN), or robotic partial nephrectomy (PN). The aim of this review was to analyze the most representative RAPN series in terms of reported oncological outcomes. (2) Methods: A systematic search of Webofscience, PUBMED, Clinicaltrials.gov was performed on 1 August 2022. Studies were considered eligible if they: included patients with renal cell carcinoma (RCC) stage T1, were prospective, used randomized clinical trials (RCT) or retrospective studies, had patients undergo RAPN with a minimum follow-up of 48 months. (3) Results: Reported positive surgical margin rates were from 0 to 10.5%. Local recurrence occurred in up to 3.6% of patients. Distant metastases were reported in up to 6.4% of patients. 5-year cancer free survival (CFS) estimates rates ranged from 86.4% to 98.4%. 5-year cancer specific survival (CSS) estimates rates ranged from 90.1% to 100%, and 5-year overall survival (OS) estimates rated ranged from 82.6% to 97.9%. (4) Conclusions: Data coming from retrospective and prospective series shows very good oncologic outcomes after RAPN. Up to now, 10-year survival outcomes were not reported. Taken together, RAPN deliver similar oncologic performance to OPN and LPN.
RESUMEN
Patients with upper tract urothelial carcinoma (UTUC) often have a delayed diagnosis and by then, present with advanced disease which has been shown to be associated with lymphovascular invasion (LVI). It has been suggested to be involved in the metastatic cascade of the disease. In this review, we provide an extensive up-to-date summary of the current knowledge about the prognostic impact of LVI in patients undergoing radical nephroureterectomy (RNU). A systematic search of PubMed/MEDLINE, Scopus, EMBASE, and Web of Science for all reports published from 2010 through 2021 was performed. We performed pooled analyses of hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs) of series that evaluated LVI as a prognostic factor in adults with UTUC who underwent RNU. The assessed oncological outcomes were disease recurrence, cancer-specific and overall survival. A meta-regression analysis was used to explore potential heterogeneity. A total of 58 series met the eligibility criteria for qualitative and quantitative synthesis. We included 29,829 patients, ranging from 101 to 2492 per study. All series were retrospective. LVI was present in 7,818 patients (26.2%). The median age of the patients was 69 years and the median follow-up was 40 months. In 40 of 58 studies (68.9%), adjuvant chemotherapy was given. The pooled HRs show that LVI predicts a greater risk of recurrence of the disease (pooled HR 1.43, 95% CI: 1.31-1.55, Pâ¯=â¯0.000; I2â¯=â¯76.3%), and decreases cancer-specific survival (pooled HR 1.53, 95% CI: 1.41-1.66, Pâ¯=â¯0.000; I2â¯=â¯72.3%) and overall survival (HR 1.56, 95% CI 1.45-1.69, Pâ¯=â¯0.000; I2â¯=â¯62.9%). It can be concluded that LVI is a common histologic pattern in surgical specimen in patients undergoing RNU for UTUC. LVI predicts a greater risk of recurrence and mortality, thus it should be carefully assessed in clinical practice to determine prognosis, and for optimal decision-making within the concept of personalized therapies.

INTRODUCTION: Therapies combining either two immune check-point inhibitors (ICIs) or an ICI and a tyrosine kinase inhibitor (TKI) have been shown to improve overall survival (OS), progression-free survival (PFS) and objective response rates (ORR) in metastatic renal cell carcinoma (mRCC); moreover, unprecedented rates of complete remission (CR) have been reported. AREAS COVERED: Among six randomized trials of ICI combinations, four have outperformed the TKI sunitinib in terms of OS. The CheckMate 214 trial investigated the combination of nivolumab (a programmed cell death protein 1 [PD-1] inhibitor) and ipilimumab (a cytotoxic T-lymphocyte antigen-4 [CTLA-4)] inhibitor). Three other trials evaluated combinations of an ICI and a TKI. These combinations are: 1) pembrolizumab (PD-1 inhibitor) plus axitinib, 2) nivolumab plus cabozantinib, and 3) pembrolizumab plus lenvatinib. This short review addresses the findings of these trials, comparing outcomes and discussing the challenges of decision-making in clinical practice. EXPERT OPINION: Not all patients benefit from ICI combinations. Predictive biomarkers and new therapeutic approaches are urgently needed to overcome treatment failures. A growing understanding of immune escape mechanisms and the interplay between the immune response and the gut microbiota may offer additional rescue strategies beyond ICIs and TKIs.

PURPOSE OF REVIEW: To perform indirect comparisons of efficacy and safety of first-line immune checkpoint inhibitor (ICI)-based combination therapies for renal cell carcinoma with sarcomatoid features (sRCC). RECENT FINDINGS: Five trials were included in our network meta-analyses comprising 568 patients. The combinations nivolumab plus ipilimumab and nivolumab plus cabozantinib achieved significant improvement of progression-free survival (PFS), overall survival (OS), and objective response rates (ORR). Nivolumab plus ipilimumab was associated with the highest likelihood of achieving a complete response. All the included combinations significantly improved PFS and ORR. The combinations of pembrolizumab plus axitinib did not show a statistically significant association with OS. Nivolumab plus cabozantinib had the highest likelihood of improving PFS and OS. SUMMARY: Our network meta-analysis demonstrates that sRCC are responsive to immune-based combinations. The dual ICI with nivolumab plus ipilimumab improved all efficacy outcomes and achieved the highest complete response rates (CRR). Although the association of nivolumab plus cabozantinib with CRR was not statistically significant, this combination demonstrated the highest likelihood of PFS and OS improvements.

BACKGROUND: Focal therapy (FT) for prostate cancer (PCa) is promising. However, long-term oncological results are awaited and there is no consensus on follow-up strategies. Molecular biomarkers (MB) may be useful in selecting, treating and following up men undergoing FT, though there is limited evidence in this field to guide practice. We aimed to conduct a consensus meeting, endorsed by the Focal Therapy Society, amongst a large group of experts, to understand the potential utility of MB in FT for localized PCa. METHODS: A 38-item questionnaire was built following a literature search. The authors then performed three rounds of a Delphi Consensus using DelphiManager, using the GRADE grid scoring system, followed by a face-to-face expert meeting. Three areas of interest were identified and covered concerning MB for FT, 1) the current/present role; 2) the potential/future role; 3) the recommended features for future studies. Consensus was defined using a 70% agreement threshold. RESULTS: Of 95 invited experts, 42 (44.2%) completed the three Delphi rounds. Twenty-four items reached a consensus and they were then approved at the meeting involving (N.=15) experts. Fourteen items reached a consensus on uncertainty, or they did not reach a consensus. They were re-discussed, resulting in a consensus (N.=3), a consensus on a partial agreement (N.=1), and a consensus on uncertainty (N.=10). A final list of statements were derived from the approved and discussed items, with the addition of three generated statements, to provide guidance regarding MB in the context of FT for localized PCa. Research efforts in this field should be considered a priority. CONCLUSIONS: The present study detailed an initial consensus on the use of MB in FT for PCa. This is until evidence becomes available on the subject.

PURPOSE OF REVIEW: To compare the safety profiles of systemic immune checkpoint inhibitor-based combination therapies that were evaluated in the first-line setting of the management of patients with advanced or metastatic renal cell carcinoma (mRCC). RECENT FINDINGS: Six phase III randomized control trials comparing first-line immune-based combination therapies to sunitinib in previously untreated patients with mRCC. Network meta-analyses were conducted to compare treatment-related adverse events (TRAEs), treatment discontinuation, and treatment-related mortality. SUMMARY: Lenvatinib plus pembrolizumab was associated with the highest likelihood of grade ≥3 TRAEs, and treatment discontinuation rates. Nivolumab plus ipilimumab was associated with the lowest rates of grade ≥3 TRAEs. However, it was associated with a higher likelihood of endocrine-related adverse events (AEs). A higher likelihood of high-grade diarrhea was associated with pembrolizumab plus axitinib and avelumab plus axitinib. All combinations showed low rates of hematological AEs.

PURPOSE OF REVIEW: The purpose of this review is to evaluate the risk of intraoperative aerosol viral transmission and the impact of updated COVID-19 guidelines on minimally invasive surgery (MIS) in Austria. RECENT FINDINGS: The current literature does not support the risk of intraoperative viral transmission nor does it suggest a harm of minimally invasive procedures in the context of the COVID-19 pandemic. However, medical societies mostly adopted a precautionary approach with a focus on protective measures. Austrian surgeons considered MIS safe during the pandemic and Austria managed to keep the initial outbreak in control. Yet, MIS programs were still affected due to the postponements of elective procedures and switches to other methods by some surgeons. SUMMARY: The postponement and cancellation of MIS caused complexities in health-care delivery in Austria, whilst the evidence to substantiate this precautionary approach is missing. It must be noted, both the guidelines and our review are limited by the scarcity of evidence. In further consequence, regional factors should be considered while taking precautions. Specific studies on the severe acute respiratory syndrome coronavirus type 2 transmission risk during MIS are urgently needed.

PURPOSE OF REVIEW: To discuss treatment decisions in the first-line setting of metastatic renal cell carcinoma (mRCC). RECENT FINDINGS: Immune check point inhibitor (ICI) combinations have replaced sunitinib as the standard of care in the first-line treatment of mRCC. Dual ICI treatment with nivolumab and ipilimumab was shown to significantly improve overall survival and objective response rates. Similarly, the ICI-tyrosine kinase inhibitor combinations pembrolizumab and axitinib and nivolumab and cabozantinib have demonstrated superiority in terms of overall survival, objective response rates and progression-free survival versus sunitinib. The lack of both comparative trials and predictive markers impedes individualized treatment decisions. Clinicians are left to make treatment choices based on clinical and biological factors. These factors may include differences in toxicity profiles, the rate of complete remission, a clinical situation that requires urgent tumor shrinkage, the presence of inflammation, histological or immune-histochemical features and others. SUMMARY: In the absence of comparative trials, clinical and biological factors may facilitate the choice between various treatment options in the first-line setting of mRCC. In addition, both the experience of the physician with a specific treatment together with patient's preferences and expectations of systemic therapy may be part of the decision-making process.

CONTEXT: There have been substantial changes in the management of patients with metastatic renal cell carcinoma (mRCC) over the past decade, with upfront immunotherapy-based combinations replacing targeted therapies. A broad range of combinations have been approved, and comparisons of their efficacy and safety are needed to guide the optimal choice of first-line therapy. OBJECTIVE: To perform indirect comparisons of efficacy and safety of first-line immune checkpoint inhibitor (ICI)-based combination therapies for mRCC. EVIDENCE ACQUISITION: We searched multiple databases and abstracts of major scientific meetings up to February 2021 to identify phase III randomized controlled trials of patients receiving first-line ICI-based combination therapies for mRCC. Progression-free survival (PFS) and overall survival (OS) were the primary endpoints. The secondary endpoints included complete response rates (CRRs), objective response rates (ORRs), grade ≥3 treatment-related adverse events (TRAEs), and rates of treatment discontinuation due to adverse events (AEs). Subgroup network meta-analyses were performed based on patients' risk group categories and programmed death ligand 1 (PD-L1) expression status. EVIDENCE SYNTHESIS: Six trials were included in our network meta-analyses comprising 5121 patients. Nivolumab plus cabozantinib had the highest likelihood of providing the maximal OS (P score: 0.7573). Lenvatinib plus pembrolizumab demonstrated the highest likelihood of PFS (P score: 0.9906) and ORR (P score: 0.9564). CRRs were more likely to be associated with nivolumab plus ipilimumab (P score: 0.8682). In patients with ≥1% PD-L1 expression, the highest likelihood of better PFS was associated with lenvatinib plus pembrolizumab and nivolumab plus ipilimumab. Nivolumab plus ipilimumab was also associated with the lowest rates of grade ≥3 TRAEs; while the highest likelihood of AE-related treatment discontinuation was associated with lenvatinib plus pembrolizumab and nivolumab plus ipilimumab. CONCLUSIONS: Our network meta-analysis suggests that combinations of ICIs and tyrosine kinase inhibitors (TKIs) provide superior PFS, ORR, and OS to ICI-ICI combinations, regardless of the on International mRCC Database Consortium risk group. However, an ICI-ICI combination could be the optimal treatment for tumors with increased PD-L1 expression. The newly introduced ICI-TKI combinations, nivolumab plus cabozantinib and lenvatinib plus pembrolizumab, showed promising activity and are likely to have an important role in the mRCC treatment strategy. PATIENT SUMMARY: The use of immune checkpoint inhibitor (ICI)-based combinations (ICI plus tyrosine kinase inhibitor and ICI-ICI) improved oncological outcomes of metastatic renal cell carcinoma. Programmed death ligand 1 (PD-L1) expression status could help guide physicians and patients to select the appropriate treatment strategy.

99mTc-PHC-102 is a 99mTc-labeled derivative of acetazolamide, a high-affinity small organic ligand of carbonic anhydrase IX (CAIX). 99mTc-PHC-102 has previously shown favorable in vivo biodistribution properties in mouse models of CAIX-positive clear cell renal cell carcinoma (ccRCC) and colorectal cancer. In this study, we aimed to explore the targeting performance of 99mTc-PHC-102 in SPECT in patients with renal cell carcinoma while also assessing the safety and tolerability of the radiotracer. Methods: We studied 5 patients with localized or metastatic ccRCC in a microdosing regimen, after the administration of a 50-µg total of CAIX ligand and 600-800 MBq of 99mTc-PHC-102. Tissue distribution and residence time in normal organs and tumors were analyzed by serial SPECT/CT scans at 3 time points (30 min, 2 h, and 6 h) after intravenous administration. Results: In the 5 patients studied, 99mTc-PHC-102 was well tolerated and no study drug-related adverse events were recorded. In the stomach, kidneys, and gallbladder, the radiotracer showed a rapid initial uptake, which cleared over time. Localization of the study drug in primary tumors of 5 patients was observed, with favorable tumor-to-background ratios. 99mTc-PHC-102 SPECT/CT allowed the identification of 4 previously unknown lung and lymph node metastases in 2 patients. Conclusion:99mTc-PHC-102 is a promising SPECT tracer for the imaging of patients with ccRCC. This tracer has the potential to identify primary and metastatic lesions in different anatomic locations. 99mTc-PHC-102 might also serve as a companion diagnostic agent for future CAIX-targeting therapeutics.

OBJECTIVE: To identify the available evidence on aerosol viral transmission risk during minimally invasive surgery (MIS) and evaluate its impact on guidelines development and clinical activity worldwide during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: We performed a scoping review on PubMed, Cochrane, the Excerpta Medica dataBASE (EMBASE), Clinical Trial Register, and the Grey Literature Repository databases, to identify reports on viral transmission via surgical smoke or aerosolisation. A systematic review of all available national and international guidelines was also performed to report their recommendations. Additionally, a worldwide transdisciplinary survey was performed to capture the actual compliance to dedicated guidelines and their impact on MIS activity. RESULTS: Based on a selection of 17 studies, there was no evidence to support the concerns of an intraoperative viral transmission via pneumoperitoneum aerosolisation. Most national surgical and urological societies either did address this topic or referred to international guidelines. The guidelines of the American College of Surgery, the Royal College of Surgeons, and the European Association of Urology Robotic Urology Section, recommended an avoidance of MIS due to an increased risk of intraoperative aerosol-enhanced transmission. The results of the survey completed by 334 respondents, from different surgical abdominal specialties, suggested a lack of compliance with the guidelines. CONCLUSION: There seems to be a dissonance between contemporary guidelines and ongoing surgical activity, possibly due to the perceived lack of evidence. Recommendations regarding changes in clinical practice should be based on the best available research evidence and experience. A scoping review of the evidence and an assessment of the benefits and harms together with a survey showed that laparoscopic procedures do not seem to increase the risk of viral transmission. Nevertheless, the few publications and low quality of existing evidence limits the validity of the review.

CONTEXT: Immune-checkpoint inhibitors (ICIs) are a mainstay treatment of metastatic renal cell carcinoma (mRCC). As not all patients benefit from ICIs, a biomarker-driven clinical decision-making strategy is desirable. OBJECTIVE: To assess the predictive value of programmed death ligand 1 (PD-L1) in mRCC patients treated with ICIs. EVIDENCE ACQUISITION: Multiple databases were searched for articles published up to April 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Studies comparing objective response rate (ORR), complete response rate (CRR), progressive disease rate (PDR), or progression-free survival (PFS) based on tumor PD-L1 status in mRCC patients were eligible. EVIDENCE SYNTHESIS: Six studies matched our eligibility criteria. Treatment with ICIs was associated with significantly higher ORRs and CRRs, and lower PDRs in patients with PD-L1-positive tumors than in those with PD-L1-negative status (odds ratio [OR] 1.84, 95% confidence interval [CI] 1.48-2.28; OR 3.11, 95% CI 2.04-4.75; and OR 0.43, 95% CI 0.31-0.60, respectively). ICI treatment was associated with significantly better PFS in PD-L1-positive patients than in sunitinib-treated patients (hazard ratio 0.65, 95% CI 0.57-0.74), whereas this was not found in patients with PD-L1-negative tumors. Compared with sunitinib, ICI combination therapy improved ORRs and PFS significantly in PD-L1-positive patients of all examined ICIs. Nivolumab plus ipilimumab had the highest likelihood of providing the highest ORR and longest PFS in PD-L1-positive patients. CONCLUSIONS: PD-L1 positivity of the tumor is associated with improved ORRs and prolonged PFS in mRCC patients receiving ICI treatment and thus helps identify mRCC patients most likely to benefit from ICI treatment. PATIENT SUMMARY: The use of an immune-checkpoint inhibitor for the treatment of metastatic renal cell carcinoma (mRCC) improved oncological outcomes, and the status of programmed death ligand 1 could contribute to guiding patients and clinicians when determining personalized treatment strategies for mRCC.

PURPOSE OF REVIEW: The role of metastasectomy in the management of metastatic renal cell carcinoma (mRCC) remains controversial. The aim of this review is to summarize and evaluate the recent findings about the surgical treatment of patients with mRCC focusing on the literature published in the last 2 years. RECENT FINDINGS: Despite the lack of randomized controlled trials, the benefit of metastasectomy in term of cancer-specific and overall survival have been demonstrated in large observational studies. Results of ongoing clinical trials evaluating the impact of combination of surgical and systemic therapies are eagerly awaited and may shed the light on a new treatment armamentarium in this subset of patients. SUMMARY: Several novel systemic agents have emerged and is continuously changing the treatment paradigm in patients with advanced RCC. However, surgical resection of the primary tumor and metastatic deposits represents a definitive cure option in well selected patients.

INTRODUCTION AND OBJECTIVES: To evaluate the prognostic role of modified Glasgow prognostic score (mGPS) for the prediction of oncological outcomes in a retrospective large multicenter cohort of upper tract urothelial carcinoma (UTUC) patients treated with radical nephroureterectomy (RNU). MATERIALS AND METHODS: We retrospectively analyzed a multicenter cohort of patients treated with RNU for clinically nonmetastatic UTUC. Multivariable logistic regression analyses were performed to evaluate the ability of mGPS to predict nonorgan confined (NOC) disease and lymph-node involvement (LNI) at RNU. Multivariable Cox-regression models were performed to evaluate the preoperative and postoperative prognostic effect of mGPS on survival outcomes. RESULTS: Overall, 2,492 patients were included in the study. Of these, 1,929 (77%), 530 (21%), and 33 (1%) had a mGPS of 0, 1, and 2, respectively. mGPS was associated with characteristics of tumor aggressiveness and independently predicted LNI and NOC at RNU (both P < 0.05). On univariable and multivariable Cox-regression analyses, higher mGPS was independently associated with recurrence-free, cancer-specific, and overall survival, both in a preoperative and in a postoperative setting. The inclusion of mGPS significantly improved the discrimination of a preoperative model for the prediction of oncologic outcomes compared to standard prognosticators. CONCLUSIONS: We found that mGPS is independently associated with clinicopathologic features and survival outcomes after RNU. Future studies should investigate the role of mGPS in a panel of preoperative markers for the prediction of NOC and LNI in UTUC patients, thus possibly improving the selection for perioperative systemic therapy.

BACKGROUND: Sunitinib has been the standard of care for patients with metastatic renal cell carcinoma (mRCC). However, nearly all patients will eventually develop resistance. Before the introduction of novel agents, few treatment options remained after sunitinib failure. Sunitinib rechallenge is a strategy based on the presumption that resistance might be only temporary. The aim of this analysis was to evaluate the efficacy and safety of sunitinib rechallenge in patients with mRCC. PATIENTS AND METHODS: Patients who had undergone sunitinib rechallenge (SU2) at the Medical University of Vienna from 2010 to 2017 were identified for the present retrospective study. The primary endpoint was the treatment duration with rechallenge (TDSU2). The secondary endpoints included the treatment duration with upfront sunitinib (TDSU1), progression-free survival (PFSSU1 and PFSSU2), overall survival (OSSU1 and OSSU2), the objective response rate in both settings (ORRSU1 and ORRSU2), and toxicity. RESULTS: A total of 31 patients were eligible. The median TDSU2 was 7.2 months, and the median TDSU1 was 17.8 months. The median OSSU1 and OSSU2 was 57.9 months and 14.7 months, respectively. The median PFSSU1 and PFSSU2 was 14.2 months and 5.6 months, respectively. The ORRSU1 and ORRSU2 was 34% and 16%, and another 48% and 42% achieved stable disease (SD), respectively. Fatigue and hypertension were the most common adverse events. CONCLUSIONS: Sunitinib rechallenge appears to benefit patients in later treatment lines. With the abundance of novel treatment options available, this approach might appear less relevant. However, novel agents are not yet available everywhere. Thus, sunitinib rechallenge could be an additional strategy to improve the outcomes of patients with mRCC.

PURPOSE: To evaluate overactive bladder (OAB) symptoms in patients undergoing diagnostic cystoscopy. Overall changes in the entire study population were assessed, as well as broken down by various subgroups. METHODS: A prospective multi-center study among consecutive 450 adults undergoing diagnostic cystoscopy was conducted. OAB-symptoms were evaluated with the validated eight-item OAB Screening Awareness Tool (OAB-V8) immediately before and on days 1, 4, and 7 after cystoscopy. Patients were distinguished between being OAB-negative and OAB-positive (< 8 and ≥ 8 sum-score, respectively). Average sum-scores and subdomains were evaluated. RESULTS: Before cystoscopy, 44.7% of patients were screened OAB-positive and 55.3% OAB-negative. Out of those being screened negative, development of de-novo OAB was noticed in 16.8%, declining to 8.1% on day 7 (p < 0.001). In patients being OAB-positive before cystoscopy, a decline of OAB-positivity was noted during follow-up (p < 0.001). No statistically significant differences were noted when broken down by gender (p = 0.92), age (p = 0.82) and type cystoscope (rigid vs. flexible, p = 0.38). Average sum-scores declined from 8.68 before cystoscopy to 6.9 during follow-up. Flexible cystoscopy was superior over rigid in four subdomains: uncomfortable urge to urinate (p = 0.04), sudden urge to urinate with little or no warning (p = 0.02), uncontrollable urge to urinate (p = 0.03), and urine loss associated with a strong desire to void (p = 0.009). CONCLUSION: OAB-symptoms are common in patients undergoing cystoscopy. Cystoscopy itself can cause de-novo OAB-symptoms. Controversially, a decline of OAB-symptoms was noted after cystoscopy when patients were screened OAB-positive before cystoscopy. Flexible scopes were superior in some subdomains.

OBJECTIVES: Polymerase I and transcript release factor (PTRF) has been implicated in cancer biology but its role in upper tract urothelial carcinoma (UTUC) is unknown. From a pilot transcriptome, we identified PTRF was significantly upregulated in high stage UTUC. Bladder cancer transcriptome from The Cancer Genome Atlas (TCGA) supported our finding and high PTRF level also predicted poor survival. We, therefore, investigated the correlation of PTRF with patients' clinicopathologic characteristics and outcomes in a multiracial UTUC cohort. MATERIALS AND METHODS: By immunohistochemical staining, PTRF expression was determined using H-score. PTRF expression of 575 UTUCs from 8 institutions, including 118 Asians and 457 Caucasians, was compared with various clinicopathologic parameters. Human urothelial cancer cell lines were used to evaluate the level of PTRF protein and mRNA expression, and PTRF transcript level was assessed in fresh samples from 12 cases of the cohort. The impact of PTRF expression on disease progression, cancer-specific death and overall mortality was also examined. RESULTS: High PTRF expression was significantly associated with multifocality (Pâ¯=â¯0.023), high pathologic tumor stage (P < 0.00001), nonurothelial differentiation (Pâ¯=â¯0.035), lymphovascular invasion (Pâ¯=â¯0.003) and lymph node metastasis (Pâ¯=â¯0.031). PTRF mRNA expression was also markedly increased in advanced stage UTUC (Pâ¯=â¯0.0003). High PTRF expressing patients had consistently worse outcomes than patients with low PTRF expression regardless of demographic variation (all P < 0.005). In multivariate analysis, high PTRF expression was an independent predictor for progression-free survival (hazard ratio [HR] 1.70, 95% confidence interval [CI] 1.07-2.69, Pâ¯=â¯0.025), cancer-specific survival (HR 2.09, 95% CI 1.28-3.42, Pâ¯=â¯0.003), and overall survival (HR 2.04, 95% CI 1.33-3.14, Pâ¯=â¯0.001). CONCLUSIONS: Results indicate that PTRF is a predictive biomarker for progression and survival and an independent prognosticator of UTUC. Elevated PTRF could probably propel clinically aggressive disease and serve as a potential therapeutic target for UTUC.

PURPOSE: To evaluate the prognostic value of BRCA1-associated protein-1 (BAP1) expression in upper tract urothelial carcinoma (UTUC), as BAP1 mutations have been associated with prognostic implications in urologic and non-urologic malignancies. METHODS: We reviewed a multi-institutional cohort of patients who underwent radical nephroureterectomy (RNU) for high-grade UTUC from 1990-2008. Immunohistochemistry (IHC) for BAP1 was performed on tissue microarrays. Staining intensity was graded from 0-3, with BAP1 loss defined as an average intensity of <â1. Clinicopathologic characteristics and oncologic outcomes [recurrencefree (RFS), cancer-specific (CSS), and overall survival (OS)] were stratified by BAP1 status. The prognostic role of BAP1 was assessed using Kaplan-Meier (KM) and Cox regression analysis. Significance was defined as p < 0.05. RESULTS: 348 patients were included for analysis and 173 (49.7%) showed BAP1 loss. Median follow-up was 36.0 months. BAP1 loss was associated with papillary architecture and absence of tumor necrosis or CIS. On univariable analysis, BAP1 loss was associated with improved RFS (HR 0.60, p = 0.013) and CSS (HR 0.55, p = 0.007), although significance was lost on multivariable analysis (HR 0.71, p = 0.115 and HR 0.65, p = 0.071; respectively) after adjusting for other significant parameters. BAP1 expression was not significantly associated with OS. CONCLUSIONS: BAP1 loss was associated with favorable pathologic features and better oncologic outcomes in univariate but not multivariate analysis in patients with high-grade UTUC. In contrast to renal cell carcinoma, loss of BAP1 expression appears to confer a better prognosis in high-grade UTUC. The role of the BAP1 pathway in UTUC pathogenesis remains to be further elucidated.
